Abstract:
The edge excitations in the fractional quantum Hall droplet are described by the chiral Lutteringer liquid theory. They can reveal the topological properties of the FQH state due to the edge-bulk correspondence. We systematically study the edge physics of the FQH states at different filling, such as 1/3, 5/2 et.al, with different methods, such as exact diagonalization, DMRG, Jack polynomials et.al and also tried different systems such as GaAs, grapheme, code atoms et.al. In this talk, I will briefly introduce our results for the edge physics in recent years.
